A 50-year old woman with right post-thoracotomy pain was referred to us for assistance with pain control. She required pentazocine 60-150 mg per day before our treatment. First, we treated her with intercostal nerve block or oral morphine sulfate. But the result was not satisfactory after five months. Then we tried intrapleural bupivacaine. An epidural catheter was inserted into the pleural space from eight intercostal space at the anterior axillary line and 10 ml of 0.5% bupivacaine was instilled. The treatment was effective for about 4-5 hours. We continued this method for 42 days with 10 ml of 0.25% or 0.5% bupivacaine once or twice a day. She felt so good from the intrapleural analgesia and could be discharged. There was no hypotension, respiratory depression, urinary retention except burning thoracic sensation. We think it is possible to use this intrapleural bupivacaine to treat a certain kind of unilateral chronic pain.
